The excessive Utilization of fossil fuels is increasing energy shortage as well as several environmental issues. Sustainable and renewable energy systems are essential for the production of cost-effective electro-catalysts that exhibit long-term durability and superior electrocatalytic performance to improve oxygen evolution reaction (OER). Delafossite oxide was recently discovered as a viable alternative to the precious metal catalysts of RuO2 and IrO2. They can serve as highly efficient electrocatalysts in OER. This study used a low-cost, simple hydrothermal method to fabricate CuCoO2-supported g-CN, which was then characterized utilizing scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The CuCoO2/g-CN nanomaterials were analyzed in a 1.0 M KOH solution using several electrochemical methods. Additionally, the kinetic mechanisms of CuCoO2/g-CN composite electrocatalyst were examined using LSV, chronoamperometry, CV, and EIS to assess stability and performance of the catalytic mechanism. Electrochemical results show a significant overpotential of 197 mV at 10 mA cm−2 Cd and a Tafel value of 34 mV dec−1, lower Rct (2.74 Ω), and greater stability for 30 h. As a result, manufactured material performs exceptionally well in the OER procedure and in a variety of potential devices.
